How to Install LibreWolf in Ubuntu 22.04/20.04/24.04 (Step by Step)

Last updated: May 4, 2024 — 3 Comments

This is a step by step beginner’s guide shows how to install LibreWolf web browser in Ubuntu and its based systems.

LibreWolf is a free and open-source web browser fork from Firefox. The browser focuses on privacy and security, and has uBlocker ad blocker out-of-the-box.

The browser website has an official guide for installing in on Debian and Ubuntu based systems. This tutorial is just a re-write with screenshots and more explanations.

NOTE: This tutorial only works on x86_64 system for modern Intel/AMD CPU architecture types.

Step 1: Install the Key

Adding 3rd party repository in Debian/Ubuntu system needs to first install the key, so your system will trust the packages from that repository.

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command:

wget -qO- https://deb.librewolf.net/keyring.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/librewolf.gpg

This command will download the key file via wget command line tool, dearmor it so the key will be un-readable, finally save it to /etc/apt/keyrings directory.

You may verify the key by running cat /etc/apt/keyrings/librewolf.gpg. And, it should output unreadable text, like the screenshot below shows you.

Step 2: Add LibreWolf Repository

LibreWolf repository so far supports Debian 11/12, Ubuntu 20.04 & 22.04, Linux Mint 20.3, 21.1, 21.2, and all their based systems. It also works in Ubuntu 23.04/23.10 by using the package for 22.04.

1. Get your system code-name

First, run command in terminal (Ctrl+Alt+T) to get the code-name of your system:

lsb_release -sc

The code-name MUST be one of una, bookworm, vanessa, focal, jammy, bullseye, vera, or uma. If NOT, then run command:

cat /etc/os-release

This command will output which version of Ubuntu (and its code-name) is based on.

2. Add LibreWolf repository

Once you got the code-name, run the command below in terminal to create & edit source file:

sudo gedit /etc/apt/sources.list.d/librewolf.sources

Replace gedit in command with gnome-text-editor for Ubuntu 24.04, xed for Cinnamon, pluma for MATE, mousepad for XFCE, or nano command line text editor that works in most desktop environment.

When the file opens, paste the line below and save it:

Types: deb
URIs: https://deb.librewolf.net
Suites: jammy
Components: main
Architectures: amd64
Signed-By: /etc/apt/keyrings/librewolf.gpg

Here you need to replace jammy with the code-name you got in last step. For Ubuntu 24.04 (Noble) and 23.10 (Mantic), just use jammy which is working good in my case.

Finally save the file. For nano text editor, press Ctrl+S to save, then Ctrl+X to exit.

Step 3: Install LibreWolf web browser

After adding the repository and key, run the command below in terminal to refresh your system package cache:

sudo apt update

Finally, install the browser via command:

sudo apt install librewolf

Once successfully installed the package, search for and launch it from start/application menu or ‘Activities’ overview depends on your desktop environment.

And, when a newer version of the browser package is released, just use Software Updater (Update Manager) to update it:

future version of LibreWolf available in Update Manager

Set LibreWolf as default web browser

For the default GNOME Desktop, open Settings (Gnome Control Center), then navigate to Default Applications in left pane. Finally, select “LibreWolf” from the drop-down box for Web.

For GNOME 46 (Ubuntu 24.04), Default Applications has been moved to “Apps” settings page.

Other desktops may have their own option to do the job. If you don’t know where to find the option, try editing the config file that works in most desktop environments. To do so:

First, open file manager and press Ctrl+H to show all hidden files and folders.
Navigate to .config sub-folder and click edit mimeapps.list file.
Finally, set librewolf.desktop for text/html, x-scheme-handler/http, x-scheme-handler/https and save file.

How to Remove LibreWolf Web Browser

To remove the web browser, also open terminal (Ctrl+Alt+T) and run command:

sudo apt remove librewolf --autoremove

Also remove the Key file as well as source repository by running commands in terminal one by one:

sudo rm /etc/apt/sources.list.d/librewolf.sources

sudo rm /etc/apt/keyrings/librewolf.gpg

And, refresh system package cache after making changes to package sources.

That’s all. Enjoy!

Make VirtualBox VMs to Have Separate Icons in Ubuntu 22.04

Last updated: April 30, 2024 — 2 Comments

I’m using Virtualbox to try out different Linux Distributions in virtual machines. It always has 2 logo icons on Ubuntu dock: one for the manager, and another for VMs.

The VM and VM manager icons on the dock are totally same, causing me to make mis-clicks frequently. And, all the opened VMs are grouped into single icon on the dock.

If you don’t like this default behavior, then it’s easy to make Virtual Virtual Machines to have separate icon per instance.

As the screenshot below shows you, after following this tutorial, every VM will have its own system logo on Ubuntu Dock:

UPDATE: This tutorial ONLY works for Virtualbox installed from virtualbox.org/wiki/Linux_Downloads.

Method 1: Disable virtualboxvm.desktop

The VM icons for Linux are handled by virtualboxvm.desktop file under “/usr/share/applications” directory. Simply disable that file will make Virtualbox VM (7.0.12 in my test) fall back to separate icon with system/distro logo.

To do so, just create an empty file with same filename under “.local/share/applications”. It will be taken in use instead of the one in ‘/usr/share/applications’ for current user only.

Option 1: Single command to create empty virtualboxvm.desktop

Ubuntu user can press Ctrl+Alt+T on keyboard to open terminal, then run the single command below to create the empty file:

touch ~/.local/share/applications/virtualboxvm.desktop

This command should work in most Linux, though running command mkdir -p ~/.local/share/applications may be required first to create the directory.

Option 2: Use text editor to create empty virtualboxvm.desktop

For those who hate Linux commands, simply search for and launch a text editor window.

Then, it should by default open an empty file (if not create one). There open menu and select “Save as”.

In next dialog, name the empty file to virtualboxvm.desktop and save it into “Home > .local > share > applications”.

The change will be applied next time you launch a VirtualBox VirtualBox.

Method 2: Edit virtualboxvm.desktop

In case the first method does not work for you, you can configure the file to make it start VM as separate process.

1. First, open 2 “Files” windows. Then drag’n’drop virtualboxvm.desktop to local folder.

In “Files” (aka nautilus), navigate to Other Locations -> Computer -> usr -> share -> applications, then, find out the virtualboxvm.desktop file.
In another “Files” window, press Ctrl+H, then navigate to .local -> share -> applications. Finally, drag’n’drop the file to this folder.

2. Right-click on the virtualboxvm.desktop file in .local/share/applications folder and click “Open with Text Editor”.

When the file opens, add --separate flag to ‘Exec’ line. So it will be ‘Exec=VirtualBoxVM --separate %U‘.

For choice, you can change the icon to Icon=virtualbox-vbox, or replace with /path/to/whatever-icon that your want. However, all VMs will use the same icon on Ubuntu Dock.

How to Restore

To restore the change, simply delete the empty file either in your file manager or by running command in terminal:

rm ~/.local/share/applications/virtualboxvm.desktop

That’s it. Enjoy!

How to Install Waterfox from official tarball in Ubuntu

Last updated: December 4, 2023 — 2 Comments

This simple tutorial shows how to install the Waterfox web browser from its official tarball & create app shortcut in Ubuntu Linux.

Waterfox is a free open-source fork of Firefox, claims to be ethical and user-centric, emphasizing performance and privacy.

The browser provides official Linux package through the portable tarball package, though a community maintained Flatpak package is also available to run it in sandbox.

Step 1: Download Waterfox Tarball

To download the package, simply go to its website via the link button below and click the “Download” button:

Download Waterfox

Once you got the package, just extract it, and run the executable file (waterfox or waterfox-bin) in the new generated folder, will launch the web browser.

Extract, and Launch Waterfox web browser

Step 2: Create App Shortcut for Waterfox

If you want to make the app icon visible in the ‘Activities’ overview search result (or application/start menu depends on your desktop environment), then follow the steps below to create app shortcut for it.

1. Move the source folder

Before creating app shortcut, it’s better to move the ‘waterfox’ folder for long time use.

For current user only, you may put the folder to anywhere in your user home. I usually create a custom folder in user home (e.g., bin, apps) or put portable apps into .local (it’s hidden, press Ctrl+H to view/hide).

In the screenshot below, I moved the waterfox folder into the custom “MyApps” folder:

For global, it’s good choice to move the folder to “/opt“, so all users in the system can launch the web browser.

In the case, right-click on blank area of the folder that contains “waterfox” sub-folder, and click “Open in Terminal”. In pop-up terminal, run command to move or copy it to opt:

sudo cp -R waterfox /opt

2. Create App Shortcut

In most Linux, the app shortcuts are handled by .desktop files located in either /usr/share/applications or .local/share/applications.

First, search for and launch your system text editor from overview or application menu depends on your DE:

When it opens with an empty document, paste following lines:

[Desktop Entry]
Version=1.0
Name=Waterfox Web Browser
Comment=Browse the World Wide Web
GenericName=Web Browser
Keywords=Internet;WWW;Browser;Web;Explorer
Exec=/home/ji/MyApps/waterfox/waterfox %u
Terminal=false
X-MultipleArgs=false
Type=Application
Icon=/home/ji/MyApps/waterfox/browser/chrome/icons/default/default128.png
Categories=GNOME;GTK;Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;x-scheme-handler/chrome;video/webm;application/x-xpinstall;
StartupNotify=true
Actions=new-window;new-private-window;

[Desktop Action new-window]
Name=Open a New Window
Exec=/home/ji/MyApps/waterfox/waterfox -new-window

[Desktop Action new-private-window]
Name=Open a New Private Window
Exec=/home/ji/MyApps/waterfox/waterfox -private-window

Depends on where you moved the ‘waterfox’ folder, change the value of “Exec” and “Icon” accordingly! Meaning replace /home/ji/MyApps to yours.

When done pasting file content and changing Exec/Icon path, press Shift+Ctrl+S to open the “Save as” dialog. Then, do:

press Ctrl+H to show hidden folders in the pop-up dialog.
navigate to home -> .local -> share -> applications. Create ‘applications’ if it does not exist.
type waterfox.desktop as the file name.
finally click Save button.

If you did the previous steps correctly, it should now show ‘waterfox’ icon in the start/application menu or ‘Activities’ overview depends on your desktop environment.

Uninstall Waterfox

To uninstall the web browser installed via the previous steps, first remove the ‘waterfox’ folder depends on where you saved it. Then, remove the waterfox.desktop file from .local/share/applications.

Install qBittorrent 4.6.2 (Qt5) in Ubuntu 22.04 (New PPA)

Last updated: November 30, 2023 — Leave a comment

This simple tutorial shows how to install the latest qBittorrent 4.6.2 (the Qt5 build) from PPA in Ubuntu 22.04 LTS.

qBittorrent has an official PPA, which however seems no longer updating for Ubuntu 22.04 since v4.6 release series.

User can choose to install the Flatpak package, which runs in sandbox. But if you prefer the classic .deb package, then here’s new unofficial PPA for Ubuntu 22.04.

While Ubuntu 22.04 has Qt6 6.2.4 in system repository, now qBittorrent requires at least Qt6 6.4. That could be the reason the official PPA stop updating for 22.04. Thankfully, Qt5 version is still supported, so I built it into PPA for those who need it.

Features in qBittorrent 4.6.x

Experimental I2P support
UI editor for the default theme
Implement torrent tags editing dialog
Allow to add new torrents to queue top
Option to stop seeding when torrent in-actived.
See HERE for more.

Install qBittorrent 4.6.2 in Ubuntu 22.04 via PPA

The PPA package uses the total same debian/rule from the official PPA. It seems working good in my case though with minor testing.

1. Add the PPA

Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/qbittorrent

Type user password (no asterisk feedback) for sudo authentication and hit Enter to continue.

2. Update system package cache

Ubuntu now automatically refresh system package cache while adding PPA, but Linux Mint does NOT.

To do it, simply run command:

sudo apt update

3. Install or Update to qBittorrent 4.6.2

If you’re using the torrent client package from either system repository or its official PPA, simply launch Software Updater (Update Manager) to update it.

Or, run the command below in terminal window to install/update it:

sudo apt install qbittorrent

Uninstall qBittorrent

To uninstall the torrent client package, open terminal and run command:

sudo apt remove --autoremove qbittorrent libtorrent-rasterbar2.0

Also, remove the unofficial Ubuntu PPA either by running command:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/qbittorrent

or by removing source line under Other Software tab in “Software & Updates” tool.

How to Install Original GA Kernel 5.15 in Ubuntu 22.04

Last updated: November 30, 2023 — 1 Comment

There are so many tutorials teaching how to install the latest Kernel, while, this one is going to show you how to downgrade to the original GA (General Availability) Kernel 5.15 in Ubuntu 22.04.

The GA Kernel is shipped by default in the first stable release of Ubuntu 22.04. By rolling out Ubuntu 22.04.1, 22.04.2, and 22.04.3, it now has Kernel 6.2 as default (next should be 6.5 in 22.04.4).

Don’t know why, but someone asked how to revert back the original Kernel 5.15. So, here’s the quick tips show you how.

Install GA Kernel in Ubuntu:

All current Ubuntu releases, including the next Ubuntu 24.04 Noble, include linux-image-generic package in system repositories for the Generic Linux kernel.

Simply press Ctrl+Alt+T on keyboard to open terminal. Then, run command to install it:

sudo apt install linux-image-generic

Run sudo apt update if the command above does not work.

Boot Your Ubuntu with Kernel 5.15

After installing the kernel package, you have to either set it as default in boot-menu or remove the HWE 6.2 Kernel.

Firstly, boot/reboot your machine, press Esc while booting to show the Grub menu. Then, select boot the Kernel 5.15 from “Advanced options for Ubuntu” -> “Ubuntu, with Linux 5.15.0-xx-generic”.

After booted into Ubuntu and logged in, verify by running command in terminal window (Ctrl+Alt+T):

uname -a

To make it default, either remove the HWE kernel by running command:

sudo apt remove --autoremove linux-image-generic-hwe-22.04

Or, use Grub Customizer to set default boot entry under ‘General settings’ tab. See how to install Grub Customizer in Ubuntu.

How to Install Ungoogled Chromium in Ubuntu 22.04 / 24.04

Last updated: May 4, 2024 — Leave a comment

This simple tutorial shows how to install ungoogled chromium web browser in Ubuntu 22.04, Ubuntu 24.04, and their based systems.

Ungoogled-chromium is a free open-source variant of Chromium web browser, that removes all Google web services.

The project was started in 2015. It retains the default Chromium experience as closely as possible. But disables functionality specific to Google domains, including Google Safe Browsing, blocks internal requests to Google at runtime by replacing Google web domains in the source code with non-existent alternatives, and strips binaries from the source code.

It also features tweaks to enhance privacy, control, and transparency. However, almost all of these features must be manually activated or enabled.

How to Install Ungoogled Chromium in Ubuntu

The project refers to OBS repository for Debian and Ubuntu packages, however, no longer updated for long time.

As far as I know, there are still community maintained Flatpak and Ubuntu PPA available for choices.

Option 1: Flatpak package

The flatpak package can be installed in most Linux, but run in sandbox and take more disk space due to run-time library.

Tips: Linux Mint 21 can directly search for and install the Flatpak package from Software Manager.

All current Ubuntu releases can open terminal (Ctrl+Alt+T) and run 2 commands below to install the browser as Flatpak:

First, run command to install the flatpak daemon:
```
sudo apt install flatpak
```

Then, install the browser package by running command:

flatpak install https://dl.flathub.org/repo/appstream/com.github.Eloston.UngoogledChromium.flatpakref

If you’re first time installing a software package as Flatpak, then you need log out and back in to make the app icon visiable.

Option 2: Ubuntu PPA

For Ubuntu 22.04, Ubuntu 24.04, the xtradebs PPA also contains the browser packages for amd64 (Intel/AMD), arm64/armhf (Apple Silicon/Raspberry Pi) CPU architecture types.

First, press Ctrl+Alt+T on keyboard to open terminal. Then, run command to add the PPA:

sudo add-apt-repository ppa:xtradeb/apps

Type user password when it asks (no asterisk feedback) and hit Enter to continue.

Linux Mint 21 users need to manually refresh system package cache after adding PPA. To do so, run command:

sudo apt update

Finally, install the web browser as .deb package by running command:

sudo apt install ungoogled-chromium

For choice, also install ungoogled-chromium-driver package for WebDriver support.

After installing the package, search for and launch the web browser from start/application menu or ‘Activities’ overview depends on your DE and enjoy!

Uninstall Ungoogled chromium

Depends on how you installed the software package, select remove it via:

For the Flatpak package, uninstall it by running command:
```
flatpak uninstall --delete-data com.github.Eloston.UngoogledChromium
```
Also, run flatpak uninstall --unused to uninstall useless runtime libraries.
For the .deb package installed from Ubuntu PPA, remove it by running command:
```
sudo apt remove --autoremove ungoogled-chromium
```
Also, remove the Ubuntu PPA, either by running command:
```
sudo add-apt-repository --remove ppa:xtradeb/apps
```
Or by launching “Software & Updates” and remove source line under “Other Software” tab.

Switcheroo – Simple & Modern GTK4 Image Converter for Linux

Last updated: November 27, 2023 — Leave a comment

Looking for app to convert your photo images into other formats? Try Switcheroo.

For batch image processing, I’d recommend to use Converseen. However, stupid simple applications are always good choices for beginners.

And, Switcheroo is one stupid simple app for converting photo images, while having modern look and feel in today’s Linux desktop.

Click ‘Open Images’ or drag’n’drop files into app window

With it, just click “Open Images” button and choose your image file/files, or drag and drop files into the app window to open them.

It shows thumbnail preview of all opened images, along with delete buttons in top-right for each images.

By using top-left ‘+’ button, user can add more images (Tips: hold Ctrl or Shift can select multiple files). And, ‘≡’ menu even provides an option to paste images from clipboard.

After opening all your photo images, click the drop-down box in the right of “Export Format” to select which file format to convert to.

At the moment of writing, it support converting image to PNG, JPG, WEBP, HEIF, HEIC, BMP, AVIF, JXL, TIFF, PDF, GIF. Though, you have to either use top-right hamburger menu or press Ctrl + H to show less popular file types.

The app’s hamburger menu

Before clicking ‘Convert’, it provides few more options, such as set background color, resize with or without aspect ratio, and change image quality. There’s also “Save To Zip” to directly output images into ZIP archive.

Instead of providing an in-app option, it pops-up file chooser dialog asks to choose where to save output images or ZIP archive, once clicking “Convert” button.

How to Install Switcheroo Image Converter

The app is available as universal Flatpak package, that can be installed in Ubuntu, Debian, Fedora, Arch, Chrome OS, and most other Linux, even including the mobile device, such as PinePhone.

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install the Flatpak daemon:

sudo apt install flatpak

Other Linux can follow the official setup guide to get Flatpak support.

2. Then, run command to install the app as flatpak:

flatpak install https://dl.flathub.org/repo/appstream/io.gitlab.adhami3310.Converter.flatpakref

As you see in the screenshot, the downside is that a small app can have 1 GB downloading due to run-time libraries (though shared).

3. Once installed, search for and launch it from your system application launcher, start menu, or ‘Activities’ overview depends on desktop environment.

First time installing Flatpak app needs a log out and back in, to make app icon visible.

4. To enable drag’n’drop support, you need to grant access permission to the folders that contain the photo images.
To do so, install Flatseal, then use it to allow access either all user files or certain folders (by adding Other files).

Uninstall Switcheroo

To uninstall the image converting application, also open terminal (Ctrl+Alt+T), then run command:

flatpak uninstall --delete-data io.gitlab.adhami3310.Converter

Also run flatpak uninstall --unused to remove useless run-time libraries.

Add Shortcut Key to Switch Monitor Input Source in Ubuntu 24.04 | 22.04

Last updated: May 5, 2024 — 1 Comment

Have 2 or more PCs connected to a single external monitor? If you run Ubuntu (or other Linux) on one of the PCs, then here’s how to add a keyboard shortcut to switch video source on the monitor.

Most external monitors today have more than one video input ports, e.g., HDMI1, HDMI2, DP1, allowing to connect with different computers at the same time.

And, they usually support DDC/CI protocol to control monitors without hitting physical buttons.

I have multiple computers connected to the single monitor.

To save desktop space, I have only one monitor on my desk, and 2 computers connected to this single monitor. One is running Windows 10 for gaming and another with Ubuntu for work.

In Windows, I use ControlMyMonitor (it’s http link, not sure if it works now) to modify monitor settings and autohotkey to setup keyboard shortcuts.

In Ubuntu and most other Linux, it’s easy to do the job through ddcutil. And, here’s the how to steps one by one.

NOTE: This tutorial is tested and works in my case in Ubuntu 22.04 and Ubuntu 24.04, though it should also works in all other Ubuntu releases, such as Ubuntu 20.04.

Step 1: Install ddcutil

For Ubuntu user, simply press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run command to install the command line tool:

sudo apt install ddcutil

Type user password when it asks for sudo authentication, though there’s no asterisk feedback.

For Fedora, RHEL, based systems, run the dnf command below instead:

sudo dnf install ddcutil

And, Arch based Linux can install it via command:

sudo pacman -S ddcutil

Step 2: setup permission

After installing the package above, i2c user group is created. You have to add current user to that group by running command:

sudo gpasswd --add $USER i2c

Not sure if required, but try to restart computer if next step does not work for you.

Step 3: Use Linux command to Switch Monitor Input Source

1. Now, run command in terminal to report connected monitors, and find out the logical display number:

ddcutil detect

In my case, it’s number 1. Usually you can skip this step if only one monitor connected.

2. Next, run command to find out the feature code, as well as its values for input source:

ddcutil --display 1 capabilities

Replace number 1 to yours according to the last command. And you can just skip for --display 1.

In the terminal output, 60 is the input source feature code for me. And, values include: 0f and 11 in hex. So, they are 0x0f and 0x11.

3. After finding out the feature code and its values, try running command to switch monitor input source:

ddcutil setvcp 60 0x11

In this command, replace 60 to yours feature code. And, replace 0x11 (its HDMI-1 in my case) to your values according which video source to switch to.

Step 4: Setup keyboard shortcut to switch input source

If the ddcutil setvcp command works for you, now you may do following steps to set keyboard shortcuts to do the job.

For GNOME (default desktop in Ubuntu & Fedora), open ‘Settings’ and navigate to “Keyboard -> Keyboard Shortcuts -> View and Customize Shortcuts”.

In pop-up dialog, select “Custom Shortcuts”, then add new shortcut with:

Name: switch monitor input source (or whatever you want).
Command: ddcutil setvcp 60 0x11 (change code 60 & 0x11 according to yours).
Shortcut: whatever key combination that you want.

Also, add another keyboard shortcut to switch back.

For other Desktop Environments, try launching “Keyboard Shortcuts”, “Shortcut Keys”, “Custom Shortcuts”, “Keyboard”, etc, for the custom keyboard shortcuts settings page.

Firefox 120.0 can import from Chromium when Both Snap Apps

Last updated: November 22, 2023 — Leave a comment

Mozilla announced Firefox 120.0 a day ago as the latest stable release of the popular web browser.

The new release continue adding new security improvements. In the right-click menu of web links, there’s now “Copy Link Without Site Tracking” to ensure that copied links no longer contain tracking information.

The ‘Privacy & Security’ setting page now has an option “Tell websites not to sell or share my data“.

For Germany users, Cookie Banner Blocker and URL Tracking Protection by default in private windows to auto-refuse cookies, and remove non-essential URL query parameters.

For Ubuntu, both Firefox and Chromium (in system repository) are Snap packages run in sandbox. Since 120.0 release, user can now import data from Chromium to Firefox, when both web browsers are installed as Snap packages.

Other changes in Firefox 120.0 include:

enhance Canvas APIs with Fingerprinting Protection for private windows.
imports TLS trust anchors (e.g., certificates) from the operating system root store.
New keyboard shortcuts to edit and delete a selected credential on about:logins.
support corner snapping for Picture-in-Picture on Windows and Linux
Various security fixes and developer improvements.

Download Firefox 120.0

The official release note as well as download link is available in the Mozilla website via the link:

Firefox 120.0

For Ubuntu users with the pre-installed Firefox package, it has been already updated to the new 120.0 release. Just check it via menu “Help -> About Firefox”.

For those who prefer the classic .deb package format, the Mozilla Team PPA has made the package for all current Ubuntu releases, however, Ubuntu 22.04 users need to manually set PPA priority.
